Being simple

We all fear darkness,
But find black charming;
We all love lightness,
But find white boring;
Our world is colorful,
But heart's colorless;
Our advises are broad,
But thinking is narrow.

Rich work hard,
To shed off their fat;
Poor work hard,
To earn some fat;
The simple things,
Are simplest to achieve;
The rich want to gain them,
The poor want to loose them.
